producer names

Official descriptionA bounded blocking queue supported by the array. This queue sorts elements by FIFO (first-in, in-out) principle. The head of the queue is the element that has the longest time in the queue. The tail of the queue is the element that has the shortest time in the queue. The new element is inserted at the end of the queue, and the queue fetch operation starts from the head of the queue to get the element.This is a typical "bounded buffer", in which the fixed-size array keeps the

Tag: Sync log uses containe col obj to start notifyIn the field of computer, producer-consumer problem (also called bounded-buffer problem) is a kind of classic multi-process synchronization problem. This issue describes two types of processes, the producer process and the consumer process, which share a fixed-size buffer as a queue. The task of a producer is to

Overviewfor multithreaded routines, the producer and consumer models are very classic models. More accurately, it should be called "producer-consumer-warehouse model". Leaving the warehouse, producers, consumers are missing a shared storage space, there is no collaboration is not a problem. Exampledefine a scene. A warehouse allows only 10 items to be stored, each time a

, so the communication between them is actually to read and write the shared resources . Of course, mutually exclusive means may be required to ensure data consistency.Tips Now I think you can understand the relevant knowledge points of Java thread synchronization.A "shared resource", such as a member variable in a class, that is referred to as thread synchronization, which is actually shared by threads in the heap or in the method area in memory in the JVM runtime.Again, this area is t

resource, it will have to mention mutual exclusion, when the producers are producing products when consumers can not interrupt the product to take away, Therefore, there is a mutually exclusive relationship, need to have a mutex to maintain, below can raise a chestnut:The list can be used as a "trading" place where the producers put the produced products into the list, and the consumers take away the products from the list:650) this.width=650; "src=" Http://s4.51cto.com/wyfs02/M00/7F/51/wKiom1c

1. Production/consumer modelProduction/consumer issues are a very typical multithreaded problem, involving the "producer", "Consumer", "Warehouse" and "product". The relationship between them is as follows:(01) The producer will stop production only when the storage is not full and the warehouse is full.(02) Consumers can only consume goods when they are in storage, while Cang wait.(03) When consumers find

The producer-consumption mode usually has two types of threads, namely several producer threads and several consumer threads. The producer thread is responsible for submitting user requests, and the consumer thread is responsible for processing the tasks submitted by the producer. The two communicate with each other th

Producer consumer problem is a kind of important model in computer, the main description is: The producer puts in the buffer the product, the consumer takes away the product. Producers and consumers can refer to a thread or a process. The difficulty of producer consumers is: For the security of the buffer data, only one thread is allowed to enter the bu

This mode improves the overall processing speed of the program by balancing the productivity of the production line and the consuming thread.Why use producer and consumer modelsIn the world of threads, the

1. IntroductionThis article describes the queues for single-producer single-consumer models. According to the content of the write queue is fixed length or variable length, divided into single-producer single-consumer fixed-length queue and single-producer single-consumer variable length queue two kinds.
